To @ZZ whom it may concern: p

lBe it known that I, WILLIAM s. Pinson, a citizen of the UnitedStates,residin et Franklin, in the county ofv Venango andiState ofPennsylvania, have invented certain, new and useful Improvements inLubricator Cups; and I do declare the following to ibo a full, clear,and exact description of the iriyention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the iigures ofreference marked thereon, which form a part of this specification. 'y

This invention relates to certain (new and useful improvements inlubricatorsfV The invention has for its object the provision of alubricator which is adapted for use in connection with steam chests,c'tylinders, and the like, where it is necessary to oil the moving partsof machinery while under steampressure. The device is also adaptged foruse in connection with gas, air, and otl'ier forms of engines and is notonly practicail in use, but is simple in construction and ,tomparativelyinexpensive to manufacture, y With the above objects in View ttiieinvenv tion finally consists in the novel construction, combination, andarrangements of ipart-s, as will be hereinafter more fully desgaribed indetail. l,

In describing the invention in dettail reference is had to' theaccompanying lrawings, forming a part of this specication-, wherein likenumerals of reference desig-nate like parts, in which- 2 Figure l is atop view of my iinpriroved lubricator. Fig. 2 is a side view of git-hesame. Fig. 3 is a sectional side view of the same on the line A B ofFig. l. Fig. 4. is al. sectional side View of the same on the line @it Dof Fig. l. Fig. 5 is a sectional plan viewl of a portion of the deviceon the line E F of Fig. 2. Fig. 6 is a sectional side view ot' thedevice on the line C D of Fig. l with the valve removed.

Referringv now to the drawings for a description of the device indetail, thfe numeral l designates the cup for confining the oil and hasformed thereon and projecting,` at right angles therefrom the tubularstem It', which terminates in athreaded end l, by wl lich the same isattached in position for use. Across the base of the cup is formed atapering opening orv seat 2, communicating with the interior of the cupand the hollow stein thereof. Fitted loosely into this seat or openingis the tapering plug-valve 3, which is held therein by means of thewasher 4 and nut 5, arranged upon a threaded shoulder-at the small endof the valve. Formed within this plu g-valve are the chambers 6 and 6',both of which are similar in form and extend clear through the plug, butare formed at right angles with one another, so that when the hand-lever7 of the valve is turned one-quarter revolution either one of thechambers is always in position to receive a limited supply of oil fromthe cup while the other one is discharging its supply into the tubularextension or stem to the point of lubrication.

rY/Vhen one chamber is discharging its contents against asteam-pressure, it is evident that the steam cannot enter the cupthrough either chamber or during rotation of the valve, as the valvewill cut oft the entrance of the steam. oil, the steam which enterstherein is able to exert an equal pressure upon both sides of the valve,especially with the addition ofthe y subchamber 8, which is formed inthe wall of the seat and aids to balance the valve. order to exhaust thesteam from the chambers during the rotation of the valve, I have'provided in the wall of the valve-seat a port 9, which extends from nearthe center of the seat to an outlet 9 beneath the washer 4. Vith thisform of lubricator I am able to feed the lubricant into the side of thesteam chest or cylinder.

I do not desire to confine myself to the eX- act construction of thedetail parts, as such parts may be modified in form and the cup providedwith a cap and one or more chambers than shown formed through the valve,

as well as other slight changes, without de-y When one chamber isdischarging IOO :a g; ennuyer the oup to close the op nin 51g' in thebase there of, independent nhainh [formed through the valve at rightangles therewith which have different positioiiie along' its length,each of which is adapted to aueeeenivelycommunicate with and receive aquantity of oil direet from the Cup as the Valve is ronated and deliverthe same into the tubular extension, an exhaust port or groove formedalong the Valve-Seat to exhaust the steam from the ohambersas the Valveis rotated, and a chamber formed within the valve-seat opposite thetubular stein for the purpose of balancing the pressure upon the Valve.
